Title: Kin selection and reciprocity are two important evolutionary theories: Post by: michelleahmed on Oct 27, 2010 Kin selection and reciprocity are two important evolutionary theories.
A. What puzzle are they both designed to solve and why is it a puzzle? B. How does kin selection solve the puzzle? C. How does reciprocity solve the puzzle? D. Explain the sense in which each predicts a facultative adaptation Title: Kin selection and reciprocity are two important evolutionary theories: Post by: bio_man on Oct 27, 2010 kin selection -> I'll help you because your related to me thus by helping you I'm really helping my own genes to multiply, I don't expect to get any direct benefit.
reciprocity -> I'll scratch your back if you scratch mine, I expect to get a direct benefit from you later as repayment for me helping you now I don't care if your related to me or not. They apply in different cases/social structures in family groups kin selection is a better explanation but in looser groups reciprocity might be more important. A character that responds to the environment is said to be phenotypically plastic. - When plasticity is adaptive, it is a facultative adaptation - Learning is a facultative adaptation. - Skin tanning is another - Response to cold, heat, altitude, & disease Title: Kin selection and reciprocity are two important evolutionary theories: Post by: michelleahmed on Oct 27, 2010 But I dont understand what puzzle it is? :/
